I love rockbox, and I've got a ton of "rockboxed " sansa players (clips/e200/fuse/c200) Bought them all on markplaats very cheap the last few years. Personally I don't really need Rockbox on my phone, but it is surely nice to have it when no other options are available.

I had the privilege to be able to test Livermorium's Moto Mod keyboard and I must say I am very impressed!
Livermorium and Chen has done great work with the keyboard! I'm happy with typing experience, I can compare it to N950 typing, it is very satisfying. Slider works nicely, snaps smoothly in and out.

If I would compare it to Gemini, I would say that Mod keyboard is done for thumb typing while holding the phone in your hand and Gemini has more computer style typing experience.

Received a battery-less version today (thanks again to @chenliangchen).

The whole construction looks weird at first, with phone part noticably heavier and thicker, but keys itself feel pretty good, even when compared to Droid 4. Overall text typing is way more comfortable than with on-screen keyboard.

As for SailfishOS, big kudos to Motorola engineers. The situation seems to be way better than what we expected. The core functionality of Moto Mods platform is handled by kernel greybus module, as opposed to Android services and frameworks.

Auto-hotplugging is disabled by default, probably to allow Mods Manager to check the plugged mod and ask user in case of uncertified one, but we can skip that on Sailfish. After it gets enabled, the kernel sees USB hub attached to USB host controller and normal USB keyboard on it, so the rest is plug-and-play (this also means you can't connect device to PC and use keyboard at the same time, but just charging works).
